." all whom t may concern Bef .it known that l, JULrUs BRELL., a citizen of the 'United States of America, residing in New York, in the borough of 'l/ianhattan, county and State of New York, have invented certain new and useful I mprovements in Garment-Fasteners, of which the following isa specification.

r'lhis invention relates to the class ofseparable fasteners for garments comprising a stud member and a soket member and com nionly known as snap buttons, and has reference especially to that species thereof in which spring catches are employeda The object of this invention is to p rovide a separable stud and socket spring fastener in which the springs have sufii# cient hold on the/'stud to maintain connection under uneven lateral strain and in which the slots engaged by the springs are` of such construction as to permit the ready release of the fastener by direct outward pull.

inthe accompanying drawing, 4Figure l represents a plan-view of my improved garment-fastener, drawn on an 'enlarged scale, Fig. 2 is a vertical longitudinal section of the'same, online 2, 2, Fig. 1, Fig.

-3 is a perspective view of the stud-member of thegarmentffastener, and Fig. 4L is a -perspective view of the socket-member of the same, Fig. 5 represents a vertical dia metrical section'of/ the two members of this fastener in engagement, the socket member being of that form' which has a cap inclosing the stud of Ithe stud member, such cap being omitted in the other figures.

. Similar letters of vrelerence indicate corresponding parts throughout the diierent iigures of the drawing.

,Referring to the drawing, a represents.

the stud-member and b the socket member of my improved garment-fastener of the snap-button class. The 'stud member a isnpmposed of a flat disk-shaped base-plate `oihi'cir-is.provided at four points with segmental openings o for being sewed onto a garment, and with a -stud o2 that is made in cylindrical, oval or other shape, and in convex shape at its'upper ".end. This stud is hollow and proyiyled with slots-a3, at diametricallyopposte points, as shown clearly in Fig. 3. rlhese slots are` broad at their bottoms and archedat their tops as shown in Fig. 5*. Thclval shape of the stud a2 serves-for the purpose ezt-forming an increased frictional connection with the opening of the socket member of the garment-fastener. The socket member b consists of a stud b1, (not shown in Figs. l

to 4l as it may be left 0H), which corresponds in general shape with the shape of the stud a2, and which is provided with an opening o2, for engagement with the binding springs s, the inner ends of which serve to engage the recesses a3 in the neck of the stud a2, as shown clearly in Fig. 1.

rlhe binding-springs s are made approxi-v mately of S-shape, the outer bends being `made larger than the inner stud-engaging bends, so as to be firmly held in position by the crimped over edges of the socket portion, while the inner ends enter the slots (i3 oit' the stud a2 and form a reliable interlocking connection therewith. A. convex outer end of each spring projects through one of the arched slots a3 in the hollow stud o2 and the wire forming said spring crosses the wall of the stud twice at the base of said slot forming two points of contact, both springs thus furnishing Afour points of contact with the stud as shown in Fig. l. When it is desired to release the fastener' a direct outward pull causes the curved springs to slide up in contact with the edges of the slots a? and the archedform thereof forces said springs outward gradually and enables the members to be separated without manual manipulation of said springs. yThe oval or disk-shaped socket member o is also provided with segv mental openings o3l by which the socket member-is attached to the overlapping portion of the garment, as' shown in Fig-4. The segmental openings in the socket member b as well as the segmental openings in the stud iiiembei are connected by narrow depressions 0Z, d1 respectively, in which the connecting portions of the fastening threads are placed, when the stud and socket members are stitchedon to the underlappingand overlap ing portions of the garment or other artic es.

@wing to the exact iitting of the stud intothe openingpf the socket member or the stud thereo and by the engagement of the saine by the inner bends of the springs, a considerable friction is exerted on the stud, so that the release ,of the stud member from the socket member, and the separation of the stud-and socket members when a one-sided pressure is exerted thereon iis-prevented. lt i requires a direct pressure on the socket member in upward dlrection on one side of the fastener for separating the two portions.

The retention of the socket member on the stud" member is furthermore secured by the engagement of theinner bends of the locking springs, by which a four-point connection, instead of a two-point connection between the parts is secured. By the increased interlocking connection of the springs of the socket member with the recessed shank of the stud member, `side-pressure and accidental opening of the garment-fastener is obtained, while they can be easily separated from each other Whenever required by exerting a uniform lifting pressure on the socket member. Furthermore, the arcfshaped opening a3 serves an additional purpose -in that it acts to gradually move the springs so as to compress them andr thereb the movement of one part in respect to t e other serves to gradually move the springs and fromv the recesses, whereby a very gradual, yet quick and efficient 'disengagement results.

l have shown one embodiment of my a very reliable hold againstl vention, but many changes may be made therein without departing from the vspirit of the invention, as shown in the appended claim. 30l I claim: A y l A separable fastener comprising a stud member including an attaching plate and a hollow stud thereon provided with arched slots in its oppositel sides, a socketlmember including 'an attaching plate having a socket adapted to be engaged by said stud, and

`springs 0n said socket member having arcshaped inner ends adapted to project through said slots and hold said members 40 firmly against separation by lateral strain, the arched tops of said slots serving to com- Y press said springs and facilitate the separation of said members by direct outward pull.

In testimony, that I claim the foregoing as my invention, I havev signed my name in presence of two subscribing Witnesses.
